I guess it's because OBSD runs a bit slower than other distros, and the overclocking is intended to compensate for this.btw I've just succeeded in swapping the internal MD with a Sandisk Extreme III 16GB CF. The system does feel faster in general. Now I need more time to set up everything again.

is it true that openbsd runs at 520 Mhz speed on the Zaurus ???or does it go from 416 to 520 itself ?is it the normal behavoiur ?

You can make the Zaurus processor run at 520Mhz via etc/sysctl.conf using:

machdep.maxspeed=520

If you comment out or change the above to 416 then it should run at the standard 416Mhz.

However, if you want the speed to be adjusted automatically then you'll have to utilize the following apm option:

QUOTE

-A Set apmd(8) to automatic performance adjustment mode. In this mode, when CPU idle time falls below 10%, or if the AC power is connected and the battery is more than 15% charged, apm raises hw.setperf as much as possible. Otherwise, when the CPU idle time is above 30% and the system is running on battery power, apm lowers hw.setperf as much as possible to reduce power consump- tion.

Supposedly you can run the Zaurus at 624MHz, but I haven't tried this. (I don't want to fry my Z)

The original Afterboot procedure in gen2's page suggests applying apmd_flags=""i.e. without any special flag to instruct how apmd behaves.

Then mathemajikian in another thread suggests using apmd_flags="-t 300" to make the power usage report more accurate.

And then the official man page apm(8) has these two interesting options:

-C Set apmd(8) to cool running performance adjustment mode. In this mode, when CPU idle time falls below 10%, apm raises hw.setperf as much as necessary. Otherwise, when idle time is above 30% apm reduces hw.setperf as much as possible to reduce heat, noise, and power consumption.

Given now the suspend/resume issue is gone, I just wonder which flag(s)would bemost usefulto Z?
